CHAPTER - I

INTRODUCTION

1.1 BACKGROUND

Nanded City is well connected by train as well as by road to Mumbai, Delhi, Hyderabad.The

River Godavari in Nanded almost bisects the city and it runs in a west to east direction.

Nanded (south) is the new added area to erstwhile Nanded Municipal Council forming

Nanded-Waghala Municipal Corporation. Nanded city is famed for its pilgrim, tourism

offerings and education facilities. Nanded ( South) has growth potential for planned

development of residential and educational facilities (Refer Exhibit-1 for location of Nanded

City in Maharashtra State)

Nanded Waghala City Municipal Corporation (NWMC) is the organization for development

of plans to prepare a long-term perspective plan for Water Supply, Sewerage and storm water

services in the city. Present water supply to the city as given in Table I.1 is 10 Mld for

population of 54,905 souls as per 2001 census. NWMC intends to implement water supply

scheme on priority to improve the water supply in the Nanded(South). NWMC therefore

invited Consultancy services from reputed consulting firm for preparation of long term

perspective plan & detailed project report for water supply scheme, which would form part of

perspective plan.

existing WTP. The nearest substation is Waghala Grid Substation which is approximately

4kM away from proposed site, 11kV dedicated feeder will be installed from Waghala grid

substation to New WTP Site.

2.7 MECHANICAL SYSTEM

2.7.1 CIDCO RAW WATER PUMPING STATION

Existing System:

The pumps at this pumping station were installed and commissioned in 1985 and pump raw

water to CIDCO WTP. There are two pumps in the pump house (one working + one standby)

each having a capacity of 580 m3/hr and head of 52 mtr.

Individual pump delivery pipe is connected to discharge header inside the pump house. One

non-return valve and one manual sluice valve is provided on delivery pipe.

Pressure gauges are installed on the pump delivery but are not in working condition.

A 5 Ton manual Crane installed for the purpose of pumping unit maintenance.

Observations:

It is observed that the pumping units are very old and excessive heating is observed.

There is no level, flow measurement instrument provided.

2.7.2 CIDCO WATER TREATMENT PLANT

Existing System

The Raw water to the treatment plant is fed from CIDCO Raw Water Pumping Station. The

treatment scheme consists of a Cascade aerator, flash mixer, 2 no. Clariflocculator, three

Gravity sand filters. Also, the water treatment plant consists of Alum handling cum dosing

of 6

system, Lime handling cum dosing system and Chlorine handling cum dosing system. This

WTP of 12 Mld was installed and commissioned in the year 1985-86.

The raw water inlet from the cascade aerator is through Parshall flume with flow meter. The

flow meter is not working.

Presently due to Algae problem, bleaching powder is dosed just after the Cascade Aerator.

Alum solution is added after the parshall flume in the WTP with a constant head dosing tank

located in the inlet channel just before the flash mixer. Flash mixer is provided for mixing

alum solution with raw water. The flash mixer is in working condition. Three tanks are

provided for preparation of alum solution with one mixer in each tank. The mixers are

corroded and need replacement. The piping and valves for the alum tanks are corroded and

need refurbishment/replacement.

Clariflocculator is provided for WTP for sedimentation. The clariflocculator are reported not

in proper working condition and breaks down frequently. The clarifier scrapers are partly

corroded.

Two tanks are provided for preparation of lime solution with one mixer in each tank. The

mixers are not in working condition. The piping and valves for the lime tanks are corroded.

Presently lime is not dosed.

The clarified water from the clariflocculator is then filtered by Three (3) gravity sand filters

each filter has an inlet isolation gate which are corroded and difficult to operate. The filter

bed valves are leaking badly. It is reported that pressure drop across the bed is very high due

to poor quality of sand media. The loss of head meter and rate of flow meter on the filter beds

are not working. The valves in the filter beds are not functioning properly and majority of the

valves are leaking from the gland and flange joints. The two Air blowers installed for back

wash of filters are in completely bad shape. One of them is not in service. Back wash is

carried out by water from the overhead backwash tank. Pure water is stored in the backwash

tank and used for backwashing of the filters.

Post-chlorination system though provided but is now completely out of service. Presently

chlorine is directly dosed from the cylinder into the pure water header. Safety kit items are not

in proper order.

Observations:

Most of the mechanical systems in the plant are non operational and thereby affect the quality

of water produced.

No proper chemical dosing is being carried out due to non existent measuring and control

system.

The chlorine is dosed in a crude way, thereby creating a very hazardous situation.

Filters are not properly backwashed, thereby reducing their output in terms of both quality

and quantity.

2.7.3 PURE WATER PUMPING STATION – CIDCO

of 6

The pumping station is designed for a configuration of 1W+1S system with each pump

capable of pumping 6 Mld of pure water. Presently both the pumps are in operation. The

pumps are vertical turbine pumps. These pumps were installed in the year 1989.

Individual pump delivery pipe is connected to a main header discharge header inside the

pump house. One non-return valve and one manual sluice valve are provided on delivery

pipe.

Two horizontal centrifugal pumps of 26 m3/hr with a discharge head of 30 m are installed to

meet the requirement of engineering college.

A manually operated overhead hoist of 5T capacity is provided for handling of equipment

located in side the pump house.

Pressure gauges are installed on the pump suction and delivery. None of the pressure gauges

are in working condition.

No flow-measuring, level measuring instrument is provided in the system

Observations:

The pumps are quite old and break down frequently and need replacement.

Flow measuring and level measuring instrument need to be installed for proper monitoring of

water pumped and for protection of the pumps.

CHAPTER – III

SYSTEM PLANNING CRITERIA

3.1 GENERAL

This Chapter discusses the basis for identifying Design Parameters to be used in the design of inlet

mains to service reservoirs and the components of distribution system covered under the project.

Design horizon has been considered on the basis of year of Gur-ta Gaddi on September, 2008.

Accordingly horizon year would be as 2023 and 2038.

3.2 POPULATION

Population figures would be used as given in City Development Plan (ILFS). The population for

the year 2038 is obtained by extending the graph given in CDP. The population for Nanded (South

of Godavari) for the year 2023 and 2038 are given in Appendix 1 Table1.

3.3 WATER DEMAND

Water demand projections are carried out with per capita rate of 135 lpcd at consumer end and

losses up ward for gross demand projections as per CPHEEO manual. Demand is given in

Appendix 1 Table-.3

3.4 INLET MAINS TO SERVICE RESERVOIRS AND TRUNK MAINS

Flow Rate

The inlet mains to service reservoirs and trunk mains will carry water for 22 hours. To cater for

emergencies, these mains are designed for 1.1 times the daily average flow. A minimum residual

head of 2.0 m is considered over the full level of the reservoir. The full supply levels of the

existing reservoirs proposed to be used in the system. The proposed reservoirs are marked on the

Exhibit-2. The inlet main system would be in the form of a tree network of pipelines supplying

water to various reservoirs. The design of the trunk system is done using Environmental

Protection Agency (EPA) net software. The inlet mains to the service reservoirs are designed to

cater projected flows for the year 2038 and are checked for intermediate (2023) flow conditions.

3.5 LOCAL DISTRIBUTION SYSTEM

Service Storage

Storage in the service reservoirs have to be provided considering balancing of inflows and

outflows and emergency including water for fire fighting. The service storage in the horizon year

2023 is worked out presuming a 22-hour water supply. A 22-hour consumption pattern based on

assessment of water consumption every hour under local conditions has been synthetically

developed and presented in Figure III.1. The cumulative inflow and outflow for a service reservoir

are depicted in Table-III.2. From this curve, the balancing storage works out to 33 percent of the

daily water supply. The total storage to be adopted for design is considered as 33 percent

including emergencies and fire fighting requirements. These figures are taken from sample studies

carried out under this assignment.

The existing storage and proposed reservoirs in NWCMC area is given in Appendix 1, Table 2.

The storage required for this satisfaction would be for about 8 hours or about 33 percent of supply,

which is for 6 hours of supply.

of 13

3.6 HAZEN-WILLIAMS C-VALUE

In existing distribution system, Cast iron pipes have been widely used in the past. As the soil strata

is black cotton soil which is of corrosive nature, recently, internal mortar lined ductile iron pipes

have been laid in NWCMC area for trunk distribution mains and local distribution mains to take

care of corrosion of pipes.

Due to corrosion, carrying capacity of cast iron pipes reduces. The deterioration of C- value with

ages for cast iron pipes would be considered as in the table given below:

The design of transmission system is carried out by considering C value of 130 for Ductile Iron

(DI) and Mild Steel (MS).

Based on material and age of the pipe, following C-values would be adopted for design of

distribution system.

Table III.1: Hazen William C -Values for different pipe materials (Distribution Pipes)

Material

Age (years)

C value

Cast iron (CI) New 100

10 90

15 80

Ductile iron (DI) New & old 120

Mild steel (Mortar lined) New & old 120

Proposed pipes

All the proposed pipelines upto 750 mm is of DI material and pipelines above 750 mm are of

mortar lined MS pipes.

3.7 PEAK FACTOR

The peak factor with the twenty-two hours consumption pattern as shown in Fig.III.2-, which is

referred earlier, will be about 2.5. This peak factor would be used in the design.

3.8 LOCAL DISTRIBUTION NETWORK ANALYSIS

Distribution System

The proposed distribution zones are planned considering coverage of the existing distribution

network of the nearby existing reservoirs. In addition to this following points have been

considered while rezoning:

i. Geographical features and ground profile

ii. Population densities

iii. Location of existing reservoirs

iv. Availability of land to build additional reservoir at existing reservoir site and at new locations

v. Feasibility of laying additional mains

vi. Manmade barriers like railways, major roads etc.

of 13

There is a large variation in demand for the year 2023 and 2038. Therefore laying of pipes now for

the year 2038 is not advisable. Hence water distribution would be design for the requirement for

the year 2023. However transmission system is designed for the year 2038 as it is to be laid once

on major roads.

3.9 RESIDUAL PRESSURES IN THE DISTRIBUTION SYSTEM

Presently the houses in the Nanded Waghala Municipal Corporation area are in the range of

Ground to Ground+1 Storied. Therefore system is designed for minimum residual pressure of 12

m at nodal points.

3.10 MINIMUM DIAMETER OF THE PIPE

The minimum proposed diameter of pipes considered in the analysis is 100 mm and no service

connections would be given from a pipe more than 200 mm dia. Wherever there is single pipeline

on a road of size above 200mm, a parallel line of 100 mm is proposed for giving consumer

connections.

3.11 MISCELLANEOUS CONSIDERATIONS

Bulk Flow Meters

After a careful study of the system’s requirements, bulk flow meters have been proposed at 12

strategic points in the system such as water treatment plants, service reservoirs and pumping

stations to monitor the quantum of water being handled at these places. Magnetic type full-bore

flow meters have been recommended

A provision is also made for bulk meter at existing stand post for measurement of flow. About 40

no 100 mm size meters are proposed in the system.

Pressure Gauges

Monitoring of the water supply system would include monitoring of the pressures and flows in the

field.

For monitoring pressures in the local distribution network in the field, it is proposed that pressure

points be made and kept ready at all important road junctions and at critical points as sudden dips

or humps. Whenever required, pressures could be monitored easily at these points.

In every zone about 5 points are anticipated. A total of 30 points are proposed.

Level Indicators

During studies conducted for identification of rehabilitation measures for service reservoirs in the

system it was noted that level indicators at many of these locations were either not in working

condition or missing. A provision is now made to have float type level indicators at all these

locations. Level indicators are proposed for all the new reservoirs.

Valves

For operation and maintenance of any intermittent supply system a minimum number of valves are

necessary. Ideally in a continuous supply system every branch should have a valve to enable

isolation of lines in stretches.

Now that NWCMC is planning for leak detection work on a large and continuous basis, the system

should have adequate number of valves to isolate the pockets.

3.12 STRUCTURAL DESIGN CRITERIA FOR ELEVATED SERVICE RESERVOIRS

Standards And Codes

The following codes (latest edition) are applicable for the design of various structures.

a) IS 456: Code of Practice for Plain and Reinforced Concrete.

b) IS 800: Code of Practice for General Construction in steel.

c) IS 875: Code of Practice for Structural Safety of Buildings – Loading Standards.

d) IS 1893: Criteria for Earthquake resistant design of Structures. (Refer 4.4 also

e) IS 3370: Code of Practice for Concrete Structures for the Storage of Liquids (Part I to IV).

.

Geotechnical Data

Detailed geotechnical investigation is proposed to be carried out at the site. From the report of a

preliminary geotechnical investigation carried out earlier, the safe soil bearing capacity for the

design and cost estimating of the ESRs can be taken as 100 KN/sq m. The detailed report and the

recommendations of the geotechnical investigation agency, after review, regards Safe Bearing

capacity, type of foundation, ground water table and other related matters, will be followed in the

design of foundations.

Loads

The ESRs for this project would be designed for the following loads –

Dead Loads

Dead loads would include the weight of all permanent construction including walls, staging,

floors, finishes, roof and staircase

The dead loads of materials would be as per IS 875 Part 1. The minimum dead loads of frequently

used materials in the design of ESRs would be considered as follows:

(a) Weight of water: 9.81 kN/m3

(b) Weight of soil (irrespective of strata

available at site and type of soil used

for filling, etc.). However, for checking

stability against uplift actual weight of

soil as determined by field test would

be considered: 20.00 kN/m3

(c) Weight of plain concrete: 24.00 kN/m3

(d) Weight of reinforced concrete: 25.00 kN/m3

(e) Weight of plaster to masonry 18.00 N/m2 per mm thickness

surface:

Live Load

Live Load would include the superimposed loads due to the use/maintenance of the ESRs not

including dead, wind or earthquake load. The live loads would be as per IS 875 Part 2. The

minimum live loads on floors for different uses frequently required in design would be as follows:

m/sec. For calculation of Design Wind Speed (Vz) the following coefficients would be adopted:

K1 = Probability Factor for a return period of 50 years = 1.0

Terrain, height and structure size factor (determined from Table 2 of IS: 875 Part 3)

Topography Factor =1.00 for sites on level ground. For sites on sloping grounds, K3 would be as

per Appendix C of IS 875 Part 3.

Vz = K1 * K2 * K3

and Design Wind Pressure

Pz = 0.06 Vz2

Where Pz = Design wind pressure in N/m2 at height Z

Seismic Load

Seismic loads would be computed according to IS 1893 -1984 for the ESRs.

As per IS 1893 – 2002, Nanded falls in Zone II of Seismic map of India. The importance factor to

be considered for design of ESRs would be taken as 1.5.

Combination of Load Cases

A judicious combination of the loads specified above keeping in view the probability of:

a) Their acting together and

b) Their disposition in relation to other loads and severity of stresses or deformations caused

by combinations of the various loads is necessary to ensure the required safety and

economy in the design of the ESRs.

Keeping the above aspect in view, the following load combinations, whichever combination

produces the most unfavorable effect in the ESRs, foundation or structural member concerned will

be adopted.

a) DL

b) DL + LL

c) DL + WL/EL

d) DL + LL + WL/EL

Where DL = dead load

LL = live load

WL = wind load and

EL = seismic load

CHAPTER – 4

PIPE MATERIAL SELECTION ASPECTS

4.1 GENERAL

This study assesses the suitability of pipes of different materials for use in water supply

systems for Nanded. Two groups of pipelines as given below have been considered.

(a) Trunk Mains/Transmission Mains (mostly 300 mm and above) between water

treatment plants and service reservoirs and

(b) Local distribution Lines (mostly 100 mm to 400 mm) down stream of service

reservoirs.

The materials covered are:

• High density polyethylene (HDPE)

• Medium density polyethylene (MDPE)

• Polyvinyl Chloride (PVC)

• Asbestos Cement (AC)

• Glass fiber reinforced plastics (GRP)

• Cast Iron (CI)

• Mild Steel (MS)

• Electrically welded steel (EWS)

• Ductile Iron (DI) and

• Prestressed concrete (PSC)

The main parameters which have been discussed are available sizes and lengths, applicable IS

codes, basic cost economics, weight, flexibility, available working pressure ratings, tensile

strength, impact strength, ease of tapping and repair, general availability in India, availability

of plant and skilled manpower for manufacturing, laying and maintenance, availability of

corrosion control techniques, ease of locating underground pipes, special bedding

requirements, laying speed and performance experience . Table-I-list the parameters of

various pipe material.

Major characteristics of various pipe materials are brought out as follows.

4.2 PIPE MATERIALS

HDPE

HDPE pipes are available in sizes up to 630 mm OD but they are commonly used up to 315

mm OD. The material is light, has very good impact strength, flexibility and corrosion

resistance. The jointing can be done by butt-welding, insert jointing or by flange jointing and

requires skilled manpower. HDPE pipes are tough and resilient and conform to the

topography of land when laid above ground or in trenches. They can bend to some extent

thus reducing use of specials like bends, elbows etc., there by reducing installations costs.

HDPE pipes are easy to carry and install because of their lightness. Metallic tags could be

fixed at regular intervals for ease in locating the pipe with a pipe locator. These pipes have

been used in India for pipeline laid under backwaters. The pipe has a very high C-value,

which does not deteriorate much with age. The bedding material has to be free and sharp

edges. Fine sand or screened excavated material is ideal. It is the costliest material as

compared to other pipes available in its range.

2 of8

MDPE

MDPE pipes are available in sizes from 20 mm to 110 mm. MDPE belongs to family of

plastic pipes. A wide range of injection moulded fittings, including toes, elbows, reducers,

caps, pipe saddles, inserts and threaded adapters are available. Metallic tags need to be fixed

at regular intervals for locating the pipe. They have a smooth surface and hence the Hazen

Williams roughness co-efficient ‘C’ is high. Thus the carrying capacity is not reduced with

age. Special care needs to be taken about the bedding material, which should be either fine

sand or screened excavated material. If laid over ground they should be adequately supported

to prevent sagging. Also, storing of the pipes needs extra care. These pipes are ideal for

service connections. Tapping of service connections can be given through a saddle only.

Smaller diameter mains are coil able and can be easily bent during installation, eliminating

the use of specials like bends, elbows etc. thereby reducing fitting and installation costs.

They are lighter in weight and can be carried to heights as on hills. They can withstand

movement of heavy traffic. This would not cause any damage to the pipes because of their

flexural strengths. They have non-adherent surface, which reject any foreign materials,

which would impede the flow.

PVC

This is available in sizes up to 250 mm. The material is light, has fairly good impact strength,

high corrosion resistance and a high C-value. The pipes are easy to carry and install because

of their lightness. They need however be protected from high temperature and ultra-violet

light and require proper handling and storage facilities. It is advisable not to lay PVC pipes

above ground to prevent discoloration, surface cracking and brittleness. PVC pipes are also

prone to rodent attack. Tapping requires saddles but requires skilled manpower. Metallic

tags at regular intervals can be provided for ease in locating the pipe with the pipe locator.

The bedding material has to be free from sharp edges. Fine sand or screened excavated

material is ideal. PVC is cheaper than CI and HDPE but more expensive than AC for sizes

available in its range.

AC

This is available in sizes of 80 mm to 600 mm. However it is commonly used in sizes of 100

mm to 600 mm. It is light, has very good corrosion resistance and a high C-value. It is the

cheapest available material. It has low impact strength. It can be drilled and tapped easily.

Provision of saddles at the point of service connections is necessary to avoid possible

leakages near connections. The pipe material is prone to attack by sulfate bearing soils. For

heavy traffic, a cover of at least 1.25 m is desirable on top of the pipe. For locating AC pipes

by a pipe locator, it is desirable to provide metallic tags on pipes at a fixed distance.

GRP

This is available in sizes of 400mm – 2400mm and has been introduced in India a few years

back. The commonly used sizes range from 400 mm to 2000 mm. These pipes have been in

use abroad for many years with satisfactory performance. The pipe is light, has good impact

strength and has a very good corrosion resistance. The bedding of these pipes has to be

formed using granular material compacted to a specific Proctor Density. This can be

achieved with proper supervision and control during laying. Jointing methods consist of

double bell coupling, flanged jointing, mechanical coupling and butt strapping which is

satisfactory but requires skilled manpower. It has a superior C-value; it is more or less on par

3 of8

with internally coated and externally gunited MS for 500 mm and larger sizes. The pipe has

greater durability and high resistance to internal and external corrosion unlike CI and MS

which would require coatings to resist corrosion. Cost of GRP pipe is about 30-40 percent

more than MS pipe with internal mortar lined and external gunited.

CI

This is available in sizes of 80 mm – 1000 mm though the commonly used range is 100mm –

1000 mm. It is widely used in water supply systems in India because of its longer life. There

are examples of cast iron mains in India, which continue to give service even after a century

of use though with reduced carrying capacity. CI pipes can be used in soils and waters of

slightly aggressive character. It would be preferable to have inside mortar lining for CI pipes

if water is aggressive. This will also improve its C-value. They are brittle materials.

Breakage's are expected in transport of pipes. They aren't available with internal mortar

lining.

MS

This can be manufactured from mild steel plates for required sizes. The material has high

impact strength due to high ductility. Specials of all kinds can be fabricated without

difficulty. Due to elasticity, MS pipes adopt themselves to changes in relative ground level

without failure and hence are suitable for laying in ground liable to subsidence. Here MS

pipe with flexible joints provides additional safeguard against failure. MS pipes being

flexible are best suited for high dynamic loading. Because of its low resistance to corrosion,

MS mains need protection from corrosion internally and externally. The internal coating

would improve the C-value. Skilled manpower is available for laying and jointing of MS

pipes. Tapping and repairs are easy. When a pipeline has to be laid over waterway or

railway, MS pipes are most suitable due to their flexibility and their light weight compared to

CI/PSC pipes. When internally coated and externally gunited it marginally differs in cost as

compared to internally coated CI pipe.

EWS

Electrically welded steel pipes (EWS) are readily available from manufacturers. The

characteristics are similar to MS pipe as discussed above. Basic cost it is slightly cheaper

than MS. However, transportation cost (from manufacturer to city & then to site) of large

diameter pipes is higher than MS pipes.

DI

Ductile Iron, also called nodular iron or spheroidal graphite iron has superior mechanical

characteristics. Ductile iron differs from cast iron by its greater tensile strength and by its

significant proof stress and elongation after yield. For protection from corrosion, inside and

outside linings are provided. Cement mortar lining material is typically applied. A seal coat

of asphalt material can also be applied over the cement mortar lining. Polyethylene internal

linings and epoxy coatings and linings are also used for special applications. Thus it has the

durability of CI and the ductile strength of MS. However it needs proper bedding and

backfilling for sizes 700 mm and above due to its thin wall design. DI has edge over the CI

pipes though they have 10 percent more cost. They are available with internal mortar lining .

As the pipes are internal mortar lined , they posses higher C-value. Therefore they have more

hydraulic capacity than CI pipes of the same diameter. It has good impact strength. Due to

this, breakages are absent in transportation. They are more corrosion resistant. Laying ,

jointing, and operation, maintenance and ease of connection is similar to CI pipes.

PSC

In India, Prestressed Concrete pipes are manufactured in sizes bewteen 300 mm and 1400

mm though at few places in size of 1800 mm has also been manufactured. The range of 400

mm – 1200 mm is most common. These pipes are used for trunk distribution mains and not

commonly used in the local distribution lines due to difficulty in tapping. The C-value of

PSC pipe is higher than that for CI. Its attraction lies in the fact it is a cheaper material as

compared to CI. It needs high degree of quality control during its manufacture. Laying of

these pipes with proper bedding and rubber rings also calls for skilled expertise and

supervision. This expertise is available only with reputed contractors. Rubber rings have to

be of good quality and storing the same without exposure to light is necessary. In addition to

producing pipes of standard specifications, reputed manufacturers can produce PSC pipes as

per the specifications of the customer. It is necessary to pre-qualify the contractors for

manufacturing and laying of PSC pipes to keep out contractors with unsatisfactory past

records of laying of PSC pipelines.

4.3 SELECTION OF PIPES

GENERAL

Final selection of pipe material depends upon the type of use it is going to be subjected to and

the cost economics. Various related aspects are covered in the ensuing paragraphs. Granular

bedding would be required for HDPE, PVC and GRP. Costs are worked out accordingly. It

is also necessary to compare the costs on a carrying capacity basis because the ‘C’ values

vary for different materials. For local distribution lines the candidate materials are HDPE,

PVC, AC, CI, MS/EWS, DI and PSC while for trunk mains the candidate materials are AC,

GRP, CI, MS/EWS, DI and PSC while for trunk mains the candidate materials are AC, GRP,

CI, MS/EWS, DI and PSC.

LOCAL DISTRIBUTION LINES

Local distribution lines are defined as the pipelines from the various service reservoirs to the

consumers. The sizes of these lines range from 100mm to 1200mm. The materials available

in this range are HDPE, PVC, AC, CI, MS/EWS, DI and PSC. Cost of AC pipes is the

lowest followed by PVC, PSC, MS and CI. AC pipes can be drilled and tapped easily leading

to unauthorized connections. The life of AC pipes is comparatively less, especially due to

8 of8

alternate wet and dry conditions the life gets shortened and the pipe suffers from frequent

bursts. The same, therefore, are not recommended. PSC pipes are available from 400mm

size but it is difficult to provide branch lines in PSC pipes and hence are not recommended

for local distribution. PVC pipes can lead to leakage losses due to rodent attack. They can be

easily tapped and encourage unauthorized consumer connections. The life of PVC pipes is

comparatively less. They are not therefore recommended. The DI pipes are recommended,

since the pipes have better hydraulic capacity, though it has marginal higher cost. DI has

merits such as its good performance record, availability of reputed manufacturers and skilled

manpower for laying, jointing and operation and maintenance and the ease of making

connections. In local distribution system, DI pipes are preferable because in general their

performance is satisfactory. DI pipes are therefore recommended in local distribution

network up to 700mm diameter. For higher diameter mains internally mortar lined and

externally gunited MS pipes are recommended.

TRUNK DISTRIBUTION LINES

The pipes carrying treated water from MBR’s to various reservoirs are defined as trunk

distribution lines, the sizes of these lines normally range from 300mm to 1200mm. The

materials available in this range are HDPE (300 to 400), AC (300 to 600), GRP (400 to

1200), CI (300 to 1000), MS/EWS (300 to 1200), PSC (300 to 1200) and DI (300 to 1200).

AC pipes are the cheapest, however downtime and cost of repairs of AC pipes would be on a

higher scale with the resultant disruption of water supply in trunk mains. They have various

disadvantages as listed above. The same are therefore not recommended. The next cheapest

are PSC pipes, but in recent years, because of bad workmanship of unqualified agencies,

there are cases of failure of these pipelines.

PSC pipes could be relied upon only if vendors are prequalified before they are allowed to

quote. This will filter out unqualified contractors. It would be necessary to prepare stringent

specifications for manufacturing and laying of PSC pipes. Cradle bedding may be laid

through out the length of PSC lines to prevent settlement. NWCMC will have to carefully

monitor the operation during manufacturing and execution stages. PSC pipes are therefore

recommended for gravity. They are not recommended for places where black cotton soil

exists. MS pipes with internal mortar lining and external guniting are recommended here.

For pumping mains MS with internal mortar ling and external guniting is recommended, as

MS pipes with welded joints are better suited to withstand water hammer than PSC pipes

because of better flexibility. Hence they are recommended. The stretches of trunk

distribution lines under roads and where reversal of flow will be taking place as per the

phased programme of laying of these lines will be of MS.

Over 700 mm size MS pipelines are proposed because PSC pipes aren’t suitable for laying in

soil strata where soil is black cotton.

CHAPTER - V

PROPOSED SYSTEM

Nanded (South) is the added area to erstwhile Nanded Municipal Council (original) forming

Nanded Waghala Municipal Corporation. Existing infrastructure of added area is lack of

infrastructure. such as Water Supply, Sewerage, Storm Water, Roads needs to be improved.

As part of Infrastructure Development, Government of Maharashtra and NWCMC are

planning to upgrade the whole infrastructure of Nanded (South) on priority.

Presently CIDCO (1.91km) area has only infrastructure facilities. Therefore the Detailed

Project Report for augmentation augmentation of Water Supply in other part of Nanded

(South).

5.1 SOURCE

Nominal capacity of this storage dam across Godavari is stated to be about 80.79 Mm

3 as per

Irrigation Department’s data. Presently some17 Mm3 storage has been earmarked for Nanded

Municipal Corporation (NWCMC) for its drinking water needs.

NWCMC has proposed to utilize this storage for its projected additional demand for drinking

water to the tune of 175 Mld. On an annual basis the additional requirements work out to

about 63 Mm3.With the present allocation of 17 Mm

3 for NWCMC already in force,

additional requirement of 63 Mm3 will require the full live capacity of Vishnupuri dam

(80.79Mm3) to be earmarked for NWCMC’s drinking water purposes.

Increasing the yield for water supply from the existing Vishnupuri storage which has been

serving vital irrigation needs, appears infeasible and impracticable given that first user rights

for irrigation has been established since long. However it can be examined whether the

present storage can at least meet the partial needs of drinking water for NWCMC. In this

context the following review is called for:

i. Review the irrigation releases pattern vis a vis agricultural demands as of present to cut

down on wasteful usages.

ii. Review the reservoir operation for the previous years.

iii. Establish the reliable yields for irrigation and water supply.

iv. Establish operation rules for “Normal” “Sub normal” and “Draught” years and identify

cutbacks on irrigation and water supply releases.

Gross water requirement for Nanded North is 50.0 Mld Water demand for the year

2023(Refer Appendix 1). It is considered that the losses in WTP and Raw Water

Transmission would be 3% each. With deduction of losses for WTP, total out put from WTP

would be 47.30 Mld. With deduction of existing treated water (50.0-12.0)=35 Mld additional

WTP would be required at Nanded (South) in the year 2023. 5.2 RAW WATER CONVEYANCE FROM VISHNUPURI

Economical analysis for pumping main diameter has been carried with 6 % interest

rate and 8% escalation rate for 2038 flows. Appendix-3 gives the details of analysis. A new raw water main of 900 mm diameter mild steel internal lined and external guniting is

proposed in addition to existing raw water main of 450 mm diameter cast iron for CIDCO

area. The proposed main would follow the alignment of existing raw water main (CIDCO) up

to Latur road, beyond; it would follow the proposed road towards Asadvan village.

of 13

Drawal of raw water for CIDCO WTP and proposed WTP at ASADVAN from

upstream of Vishnupuri dam-Jackwell:

Existing jackwell at Vishupuri would be used for pumping raw water to proposed WTP plant

Existing 600 mm Reinforced Cement Concrete (RCC) inlet pipe to jack well for raw water is

adequate to draw of 50 Mld raw water from the reservoir. For drawal of raw water(12.75Mld)

for CIDCO WTP, existing two number pumps would be replaced with same capacity of new

pumps. Additional pumps 3 nos.(2+1) would be housed in the same jackwell to pumped 38.0

Mld raw water to proposed Water Treatment plant at ASADVAN village

5.3 TREATMENT PLANT AT ASADVAN VILLAGE

The Existing Water Treatment Plant after rehabilitation will cater to the water requirement of

year 2006. Then onwards New Water Treatment Plant would be required to cater future

demand. Hence proposed Water Treatment Plant (35 Mld) would be planned for the water

requirements of year 2023.

Economical analysis for different alternative for location Water Treatment has been

considered to evaluate the appropriate location of WTP. Finally WTP at Asadvan village

would be considered.

Two alternatives are considered while locating proposed WTP at Asadvan village and

Fattejanpur Economics analysis is carried out to identify the economical site for WTP (Refer

Appendix-3

Appendix-3 indicates that net present value with 6% interest and escalation rate of 8% per

annum would be less by 30 crores when WTP selected at ASADVAN village.

Existing Water Treatment Plant at CIDCO township consist of following treatment units.

1. Prechlorination

2. Aeration

3. Alum dosing

4. Clarification

5. Filtration

6. Post chlorination.

The same treatment process shall be adopted for the proposed Water Treatment plant at

Asadvan village.

Schematic flow diagram of the proposed water treatment plant at Asadvan is given in fig V.1.

Godavari Raw Water Analysis Report is enclosed Table V.1 a & b. However, seasonal

variations are not available. In the dry season the raw water is likely to be quite clear due to

natural settling in the Basin of Godavari River. However, in monsoon the water is likely to

become turbid. With silting in the river stretch increasing over a period of time, the water will

become more turbid. The water treatment plant shall be designed to suit range of raw water

quality given in Table V.1 a

CHAPETR - VII

BASIS OF COST ESTIMATE

7.1 COST BASIS FOR PROPOSED WORKS Project cost is estimated based on Schedule of Rates (SOR), Maharashtra Jeevan Pradhikaran

(MJP) for the year 2005 – 06 Public Works Department, Government of Maharashtra. Also

the data available on soil characteristics and physical data such as ground level, location of

road, waterways etc. are considered. It is essential to undertake detailed soil investigation and

survey prior to detail engineering. The total cost estimate at present may have a small

variation at a later stage, which could be covered under physical contingencies.

7.2 WATER SUPPLY SYSTEM

PROPOSED WATER TREATMENT PLANTS

Cost of the proposed treatment plant is arrived on Mld basis. MJP DSR Cost of 35Mld WTP

is 2.76 Crores, which works out to be 7.88 Lacs per Mld. MJP’s per Mld cost seems to be on

lower side. As per TCE’s experience in similar projects (Nagpur Municipal Corporation), the

cost of 100 Mld Treatment Plant including Clear water pumping station is 14.5 Crores as per

the work (Year 2004) awarded cost, which works out to be Rs. 14.00 lacs Per Mld. This forms

the basis of cost estimates of WTP. This cost includes electrical components and mechanical

component of the WTP.

SERVICE RESERVOIRS IN THE CITY

Quantity estimates is prepared for elevated service reservoir. Unit rate for concrete is referred

from SOR. Reinforcement is considered as per norm of Indian standard specifications.

Detailed cost estimation for each reservoir has been worked out for various capacities of the

reservoirs on the basis of structural design and analysis done in STAAD.Pro. The estimates of

the ESRs have been given in Appendix 4.

Based on the estimates per litre ESR cost works out to be Rs.3. For the similar work of ESRs,

the awarded per litre ESR cost was Rs. 4. Hence provision of cost for the ESR s is made in

cost estimates on the basis of Rs. 4.00 per litre.

TRUNK SYSTEM

D.I/MS. pipe is proposed for the additional / proposed pipes required in the transmission

system and distribution system within the city. DI pipes are internal lined and MS pipes are

with mortar internal lined and external gunited.

Cost per meter length is inclusive of following components.

• Ex factory cost of pipe

• All taxes (central & local)

• Freight

• Unloading from train

• Loading into truck

• Transport to site

• Unloading

• Stacking

of 2

LAND ACQUISITION

Presently land for all proposed 6 elevated service reservoirs, proposed WTP is not in

possession of NWCMC. Requirement of land for reservoir would be one hecture/reservoir.

For WTP, land of 4 hectares would be required However the NWCMC has indicated that the

land would be made available for construction of elevated reservoirs and WTP. Therefore no

cost provision is made for land acquisition.

DISTRIBUTION SYSTEM

The existing distribution system is reorganised into existing and proposed zones. The analysis

has been carried out for the equi-distribution of water.

For the cost estimates of the pipes, 100% soil is considered for excavation. Clear cover of 1m

is considered for excavation.

Cost of special is considered on weight basis. The valves cost is estimated on the basis of

actual number basis in the system. (Refer Table 7.4 Appendix 4)

EXISTING WATER TREATMENT PLANT AND PUMPING STATION

Cost of Rehabilitation of existing WTP & Pumping Station are calculated on the basis

quotation called from the reputed vendors for Urban Water Supply and Environmental

Improvement in Madhya Pradesh Project and Maharashtra Jeevan Pradhikaran ‘District

schedule of rate’ for Aurangabad region.

REINSTATEMENT OF ROADS

After pipes are laid in position, the road is required to restore in original position. Item of road

reinstatement is considered for all pipes bitumen material. Rate analysis is carried out for road

reinstatement by bitumen l. (Refer Table 7.8 Appendix 4)

INCIDENTAL COST FOR WATER SUPPLY ARRANGEMENT FOR PILGRIMS

Tri cenetarity function of Guru Govind Singhji (Gur-ta Gaddi) would be celebrated in

September 2008. Large numbers of pilgrims are expected to attain this function. The water

supply arrangement would be required to provide the water. Hence cost provision of 2 Crore

is made.

The Detail Costs are given in Appendix 4.
